CANCER IS WORSE THAN YOU THINK.
Teresa thought that being diagnosed with cancer was the worst thing that could happen to her. But as she comes to grips with the inevitable, she starts to see horrible, vicious little monsters feasting on the people around her. They cling to necks, nibble at flesh, burrow into bellies and brains, and are completely invisible to their hosts.
What are these creatures? And are they the cause of illness and disease, or are they just preying on the weak?
Teresa is the only one who can see them, so she may be the only one who can fight them. Lucky for her, she has nothing to lose.
